F. Stern et al., COMPUTATION OF VISCOUS-FLOW AROUND PROPELLER-BODY CONFIGURATIONS - SERIES-60 C(B)=0.6 SHIP MODEL, Journal of ship research, 38(2), 1994, pp. 137-157
Validation of a viscous-flow method for predicting propeller-hull inte
raction is provided through detailed comparisons with recent extensive
experimental data for the practical three-dimensional configuration o
f the Series 60 C(B) = 0.6 ship model. Modifications are made to the k
-epsilon turbulence model for the present geometry and application. Ag
reement is demonstrated between the calculations and global and some d
etailed aspects of the data; however, very detailed resolution of the
flow is lacking. This supports the previous conclusion for propeller-s
haft configurations and axisymmetric bodies that the present procedure
s can accurately simulate the steady part of the combined propeller-hu
ll flow field, although turbulence modeling and detailed numerical tre
atments are critical issues. The present application enables a more cr
itical evaluation through further discussion of these and other releva
nt issues, such as the use of radial- and angular-varying body-force d
istributions, the relative importance of turbulence modeling and grid
density on the resolution of the harmonics of the propeller inflow, an
d three-dimensional propeller-hull interaction, including the differen
ces for the nominal and effective inflows and for the resulting steady
and unsteady propeller performance. Also, comparisons are made with a
n inviscid-flow method. Lastly, some concluding remarks are made conce
rning the limitations of the method, requirements and prognosis for im
provements, and application to the design of wake-adapted propellers.
